How to use sliding window technique to detect one single line

I've a text documents and I've detected objects using bounding boxes. Now I want to join the bounding boxes of a line. So how to use the sliding window technique for this??

Why do you keep posting (almost) duplicate questions? And why do you ignore the advice from the tutorial?

I didn't get answer for the previous question.so I posted it again.

Question is not clear....can you explain a bit more? Pictorial would be more good.

In cases like that, post a reminder in the previous question, not a new question.

@walter

Okay from next time I'll do the same

[KSSV]

Get them with multiple windows and arrange them into a line.....

@kssv

I don't know about sliding window.can you please provide me the code???

Use nlfilter() to apply nonlinear algorithms to sliding windows.

That said, there are some algorithms that can be much more efficiently calculated by using conv2() or morphological operations.
